Manual Trunnion Mounted Ball Valves

Introduction

Trunnion mounted ball valves, widely used for high pressure applications, feature bonnet bolted design and excellent resistance to abrasion. These valves are specifically designed with a fixed ball and seat ring structure, which results in stable sealing performance and extended service life. Thanks to this design, the valve seat is protected from excessive pressure, ensuring reliable operation over time.

Features

Operating the ball became effortless thanks to the application of dual bearings, which significantly lessened friction.

In order to provide a reliable seal, the stainless steel valve seat is fitted with a PTFE sealing ring that is resistant to both high and low temperatures. To ensure that the sealing ring is adequately compressed, a spring is installed at the end of the valve seat. This provides the required pre-tightening force to keep the seal in place. The use of these materials ensures that the valve is able to withstand a wide range of operating conditions and provides long-lasting performance.

The ball valve has a fireproof sealing ring that forms a metal-to-metal seal between the ball and the valve seat in the event of a fire, as per the established standards of AP16FA and API607.

When the pressure within the valve cavity becomes excessively high and surpasses the spring's pre-load, the ball will move away from the valve seat, causing automatic pressure relief to occur. This is a safety mechanism that prevents any potential damage to the valve or the surrounding equipment due to high pressure buildup. The valve's design allows for it to respond quickly to pressure changes, ensuring that the system remains stable and efficient at all times.

There are drain holes in place along the valve body to inspect for any leakage from the valve seat.

Maintenance

To maintain the optimal condition of your valve, it's crucial to pay attention to its storage environment. It's recommended to store it in a well-ventilated and dry room, ensuring that both ends of the passage are closed off. This will prevent moisture and debris from entering the valve, ensuring that it's ready for future use.

It's important to conduct regular inspections of the valve and make sure to remove any dirt buildup. Applying anti-rust oil to the surface can also help preserve the valve's condition. Taking these steps can ensure that the valve operates efficiently and safely over time.

Regular checking and maintenance are necessary to ensure the proper functioning of the valve once it has been installed and put into use. Thus, it is important to keep a close eye on the valve and carry out repairs whenever needed.

To ensure the optimal performance of the valve, it is important to inspect the sealing surface for any signs of wear. If the sealing surface is found to be worn, appropriate measures should be taken based on the situation. This may involve repairing the surface or replacing it altogether. It is crucial to address any issues with the sealing surface to uphold the efficiency and functionality of the valve.

To ensure the valve's performance, it is essential to conduct a thorough test on its sealing capabilities. Proper evaluation of the valve's sealing performance is crucial for its overall efficiency and functionality.

During operation, it is essential that the valve is in good condition. The flange and bracket bolts must be complete, and there should be no damage to the threads. Furthermore, it should not have any looseness, ensuring the equipment operates smoothly.

It is imperative that the packing gland be properly aligned and not have any gaps before being tightened. Any skewing or lack of pre-tightening gap can have negative consequences and should be avoided at all costs.
